BOOT OR SHOE SOLE PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 442,241, dated D Application filed March 12, 1890.

To aZZ whom it may concern:

Be it known that I, AUGUST F. SCHURR, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Boot or Shoe Sole Protectors; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improvementin boot or shoe sole protectors constructed of metallic plates provided with protuberances, intermediate air-holes, and a flange project- I ing around the soles of boots or shoes as a protection thereto.

My invention has reference to a metallic sheathing or cover for the soles and heels of boots or shoes; and the invention I have plate longitudinally near the center by a series of wave-line interjoining recesses and projections which fit closely one into the other, covering the same by means of an exterior imperforate plate, hinging the sectional parts of the protector at one end and at the opposite end securing them together by means of a locking device hereinafter described and shown.

In the accompanying drawings, Figure 1 represents a shoe provided with my improved sole and heel protector. Fig. 2 shows that side of the protector next the sole of the shoe closed and locked together. Fig. 3 is the same unlocked and slightly separated ready to be applied to a shoe. Fig. is an enlarged dia' gram of so much of the inner surface of the heel-protecting plate as is necessary to show its construction.

To putmy invention into practice so faras it relates to the sole of a shoe,I construct two metallic plates A 13, that are joined together on a wave-line, the projections to of one plate fitting into the depressions b of the other plate. Near that partintended for the toe of the shoe the plates are united by means of a pivot c, forming a hinge at that point, which enables the plates to be separated along the wave-line a short distance the extent of such made consists in dividing such protecting-- ecember 9, 1890.

movement being limited by a pin (Z in one plate that fits into a curve slot 6 in the adjoining plate. The adjoining ends of the plates A B most remote from their pivotal point e are provided with a peculiar locking device consisting of an eccentric f, turning around a pivotal point, so that when turned in one direction it will securelylock the plates together, and when turned in the opposite direction unlock and separate them a little distance to make them easily detachable from the shoesole and ready to be applied to the same or another shoe. The outer surfaces of both of these plates are studded or provided with obtuse protuberances h,preferablyof star shape, to prevent the wearer slipping, and between these obtuse protuberances h the plates are provided with a number of holes z", through which air will pass to ventilate the sole of the shoe. Each plate is formed at its outer edge with a flange 7.3, intended to catch over the edge of the shoe-sole, so that when the plates are locked they will be held firmly in position thereon. The lock end of one plate is also provided with a pin 7., which moves in a short slot m in the adjacent plate to prevent unnecessary separation of the plates at that point. The eccentric is rigidly fixed to a stem of one of the star-shaped protuberances directly opposite thereto on the reverse side of the plate, so that the eccentric may be retated on the application of a little wrench or properly-shaped key. To exclude earthy matter or hard substances from gaining access to the wave-line point of separation between the plates, such wave-line pointis covered by a suitable plate 21, extending the entire length thereof. It is also provided with anumber of star-shaped protuberances similar to those on the other plates.

As the plates intended for the heel are similar in construction to those used on the sole of the boot or shoe, being different only in size and form, the description of one is deemed to be sufficient for both.

Having thus described my improvement, what I claim is- The combination of two plates edge to edge, each edge a serpentine line, a number of protuberances on the ontersurface of each plate, in the opposite direction unlock and separate IO a number of holes through the plate between them. said protuberances, a pin on one plate fitting In testimony whereof I have hereunto set into a curved slot in the adjoining plate, a my hand this 6th day of March, A.
